Hi guys Zuk Z1 still creating problems. I am using lollipop on my Zuk Z1..it has creating problems one by one in day by day...1 Fingerprint is not working. 2 when someone is calling me I just rejected that call or someone miss call me either when I call someone after I click end call the phone will be reboot.. sometimes in that reboot the phone touch will not work so press the power button till reboot..press min 5 to 10 seconds...

one day I will install the twrp recovery and installed that zuk 2.5 Nougat version Multilanguage

it's very very fast..I'm sure you will be really amazing about the speed of your phone

I recommend to try zui from for zuk z1... if Fingerprint not working il lollipop it's also not work in zui and u touch not work.... sometimes reboot when call end...better than lollipop
